PLEASE ANSWER! Given the functions f(x) = x2 + 6x - 1, g(x) = -x2 + 2, and h(x) = 2x2 - 4x + 3, rank them from least to greatest

Ratling [72]

Answer:

he rank from least to great based on their axis of symmetry:

0, 1, -3 ⇒ g(x), h(x), f(x)

So, option C is correct.

Step-by-step explanation:

A quadratic equation is given by:

$ax^2+bx+c =0$

Here, a, b and c are termed as coefficients and x being the variable.

Axis of symmetry can be obtained using the formula

$x = \frac{-b}{2a}$

Identification of a, b and c in f(x), g(x) and h(x) can be obtained as follows:

$f(x) = x^2 + 6x - 1$

⇒ a = 1, b = 6 and c = -1

$g(x) = -x^2 + 2$

⇒ a = -1, b = 0 and c = 2

$h(x) = 2^2 - 4x + 3$

⇒ a = 2, b = -4 and c = 3

So, axis of symmetry in $f(x) = x^2 + 6x - 1$ will be:

$x = \frac{-b}{2a}$

x = -6/2(1) = -3

and axis of symmetry in $g(x) = -x^2 + 2$ will be:

$x = \frac{-b}{2a}$

x = -(0)/2(-1) = 0

and axis of symmetry in $h(x) = 2^2 - 4x + 3$ will be:

$x = \frac{-b}{2a}$

x = -(-4)/2(2) = 1

So, the rank from least to great based on their axis of symmetry:

0, 1, -3 ⇒ g(x), h(x), f(x)

So, option C is correct.

Twenty years ago a small town in Texas had a population of 10,000. The population has increased 8% each year since then. Predict

fenix001 [56]

Answer: After 10 more years i.e. after 30 years, the population of the town will be 100626.57 approx.

Step-by-step explanation:

Since we have given that

Initial population 20 years ago = 10,000

Rate of growth = 8%

Number of years = 10+20 = 30 years

According to question, we will use "Compound interest":

$Amount=P(1+\frac{r}{100})^n\\\\Amount=10000(1+\frac{8}{100})^{30}\\\\Amount=10000(1+0.08)^{30}\\\\Amount=10000(1.08)^{30}\\\\Amount=100626.57$

Hence, After 10 more years i.e. after 30 years, the population of the town will be 100626.57 approx.
